Description
Technical field
The utility model relates to a kind of composite vertical current artificial wetland structure processing chemical fiber waste water, belongs to sewage treatment area.
Background technology
Chemical fiber waste water is that a kind of organic content is high, colourity is high, the poisonous organic wastewater with difficult degradation thereby that biochemical property is poor, containing a large amount of DMAC(N, N-N,N-DIMETHYLACETAMIDE), DMF(N, dinethylformamide) and the hazardous and noxious substances such as other aldehydes, cyanogen class, phenols, nitrile, alkanes, directly discharge, to very serious by receiving the pollution of water surrounding. it is reported, the COD concentration of wet acrylic fiber production wastewater is between 200-1000mg/L.DMAC and DMF is the principal pollutant of chemical fiber waste water, the two stable chemical property and bio-refractory, determines it once enter in environment, will bring long environmental pollution.At present, the method extensively adopted for DMF and DMAC has: extraction-absorption method, supercritical water oxidation method, Inner electrolysis and photochemical catalytic oxidation etc.The not good or complicated operation of these methods or treatment effect, finding a kind for the treatment of process efficient, simple to operate becomes the problem that such waste water of process needs solution badly.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of composite vertical current artificial wetland structure processing chemical fiber waste water, to solve the deficiencies in the prior art.
The technical solution of the utility model is: a kind of composite vertical current artificial wetland structure processing chemical fiber waste water, mechanical grille pond is communicated with equalizing tank, coagulation floatation, homogeneous pond, neutralization tank and coagulative precipitation tank successively, coagulative precipitation tank top is communicated with primary vertical artificial wetland, then secondary sedimentation basins is communicated with, secondary sedimentation basins the other end top is communicated with secondary vertical artificial wetland, secondary vertical artificial wetland connected set pond, all plants purifying plant in each artificial swamp pond.
In mechanical grille pond, sewage approach axis sets gradually the coarse rack of 20 ㎜ and the fine fack of 5 ㎜.
Primary vertical artificial wetland comprises primary vertical artificial wetland downstream tank and the up pond of primary vertical artificial wetland.
Secondary vertical artificial wetland comprises secondary vertical artificial wetland downstream tank and the up pond of secondary vertical artificial wetland.
The purifying plant of primary vertical artificial wetland and the plantation of secondary vertical artificial wetland is giantreed, cyperus alternifolius, spot thatch, Fructus Sapindi Mukouossi or Spiked Loosestrife.
